SPECIFICATION forming part of Letters Patent No. 599,543, dated February22, 1898. Application filed June 19, 1897. Serial No. 641,469. (Nomodel.)

To all whom t may concern.'

Be it known that I, JOHN WHITAKER, a citizen of the United States,residing at Schenectady, in the county of Schenectady and State of NewYork, have invented certain new and useful Improvements in Supports forIncandescent Electric Lights, of which the following is a full andcomplete specication, such as will enable those skilled in the art towhich it appertains to make and use the same.

This invention relates to supports for incandescent electric lights; andthe object thereof is to provide an improved flexible device of thisclass which is adapted to serve as a support for such lights in anyposition and which is particularly adapted for use in connection withwhat is known as an incandescent stand lamp or light.7

In the drawings forming part of this specification I have shown myinvention applied to an incandescent stand lamp or light, and theinvention is fully disclosed in the following specification, of whichthe accompanying drawings form a part, in which the separate parts of myimprovement are designated by the same numerals of reference in each ofthe views, and in which- Figure l is a side View of my improvedincandescent stand-lamp5 Fig. 2, a section of a part thereof; and Fig.3, a view similar to a part of Fig. 1, showing a modification.

In the practice of my invention, as shown in the drawings, I provide abase 5, which is preferably provided with an upwardlydirected extension6, and I also provide an ordinary incandescent electric -light bulb 7,which is provided with the usual head 8,which is provided with a tubularscrew-threaded neck 9, in which is secured a detachable screwthreadedtube 10, and my improved standard, holder, or support consists of aspring-coil11, which is preferably composed of closely wound or coiledwire of steel or similar material and on which is mounted a plurality ofseparate sections 12. The opposite ends of the spring-coil 11 arerigidly secured in the base 6 and the tube 10, and the detachablesections l2 of the standard, holder, or support are preferablyconcavo-conveX in form and mounted on the spring-coil 11, preferably inthe position shown in the drawings, in

which the convex surfaces thereof are die rected upwardly.

The separate sections 12 of the standard, holder, or support are held inclose connection by the spring-coil 11, and it will be understood thatsaid standard, holder, or support may be turned or twisted into any de`sired form, so as to hold theincandescent electric-light bulb in anydesired position by simply turning said holder, standard, or supportinto the form or position desired, the friction between the separatesections 12 being such as to hold the incandescent electric-light bulbin an upwardly, laterally, or downwardly directed position, as will bereadilyunderstood.

My invention is not limited to the exact form of the separate sections12 of the standard, holder, or support herein described, the only objectin this connection being to provide separate sections for this purposewhich are adapted to move one upon another, as hereinbefore described,and which are held together by friction.

The conductor-wires 18 and la are also preferably passed through thestandard, holder, or support, as shown in Fig. 2; but this arrangementof said conductor-wires, although the one preferred, is not essential,as the same may be connected with the head of an electric-light bulb inany desired manner.

It will also be apparent that the base 5 is not absolutely essential, asany other device suitable for this purpose may be employed, and theholder or support may be suspended from a ceiling' or connected with awall, and other changes in and modifications of the construction hereindescribed may be made without departing from the spirit of my inventionor sacrificing its advantages.

Any suitable means may be provided for increasing the friction betweenthe separate sections 12 of the standard, holder, or support, and forthis purpose a screw-threaded collar maybe mounted on the tube 10, .andit will thus be seen that I accomplish the object of my invention bymeans of a device which is simple in construction and comparativelyinexpensive.

The spring-coil11 is not an absolutely essential feature of myimprovement, and in Fig.

IOO

3 I have shown a modified form of construen tion in which the separatesections 12 consist of the balls or spherical bodies 13 and 14, one ofwhich is sin aller than the other and which are connected in line, andthe larger ball or body is cut away at one side, asshown at 15, and isprovided with a spherical cavity or recess 16, into which the smallerball or body is adapted to be inserted, and the larger balls or bodies13 are composed of elastic material, and when the smaller balls orbodies 14 are inserted thereinto they are held therein by friction, thisform of connection being what is known as an ordinary ball-and-socketjoint. The balls or bodies 13 and 14 of which the separate sections 12are composed are preferably in this form of construction formedintegrally, and it will be apparent that any desired number of thesesections may be connected, so as to make the standard, holder, orsupport as long as necessary.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- 1. A standard or support for incandescent electriclights, consisting of a base, a springccil secured thereto, anincandescent electric light provided with a tube which is detachablyconnected therewith by means of a screw-thread, and with which saidspring-coil is connected, and a plurality of separate frictionalsections mounted on said coil, substantially as shown and described.

2. A standard or support for incandescent electric lights, consisting ofa base, a springcoil secured thereto, an incandescent electric lightprovided with a tube which is detachably connected therewith by means ofa screw-thread, and with which said springcoil is connected, and'aplurality of separate frictional sections mounted on said coil, andconductor-wires which are passed through said base, and saidspring-coil, substantially as shown and described.

3. A standard, holder or support for incandescent lights, comprising abase provided with a semispherical socket on the upper side thereof, aplurality of separate detachable sections each of which consists of alarge and small spherical portion, the large spherical portion beingprovided with a semispherical socket, said sections being adapted to beheld together by friction, and means to secure an incandescent light tothe upper end thereof, substantially as and for the purpose described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 14th day of June,1897.

JOHN WHITAKER.
